It depends on the alcohol content, but most wine will freeze at about 15 to 20 degrees F, and it would need to stay at that temperature for a while before it freezes solidly. Alcohol's freezing point is lower than water, but as the water content of the wine begins to freeze, it will begin to expand, and this will put a lot of pressure on the cork, which might begin to be pushed out, and on the bottle, which might crack. Don't freeze your wine bottles!
